- An eventual transition to total cloud storage/streaming for Xbox content - but importantly with devices in the home needed to access that content

- More relationships with TV operators and content firms

Whether real or not, the 56-page document reads like a sensible wish-list for Xbox platform growth and development.

The document talks often about the 'Xbox 720' - a term for the 360 successor often used by the media and third-parties but never explicitly used by Microsoft on the record. 720 is said to have a target launch of 2013 and competitive $299 pricing. Further detail talks of Blu-ray functionality and True 3D, with a device 'six times' more powerful than the 360 with up to eight ARM or x86 cores at 2GHz each, 4GB of DDR4 memory. It's also backwards compatible, with three Power PC cores, at 3.2GHz.

Then there's 'Fortaleza Glasses', which seems to be a concept for special augmented reality goggles that connect to Xbox at first over wi-fi and later on via 4G in SKU upgrades. If fake, at least the hoaxer at least followed some logic - Fotaleza is the state capital of Northern Brazil's Ceara. Project Natal, the codename for Kinect, took its name from a Northern Brazil capital too, and was chosen by Kinect engineer-creator Alex Kipman.

With all of that combined, the document claims the next Xbox is "The ONLY box you need for premium living room entertainment." If you've been following Microsoft's corporate line for Xbox that line, if nothing else, proves whoever wrote this document has done their homework.

To reiterate: it's not been confirmed as to whether or not the document itself is originally a draft presentation, something Microsoft actually used, or an elaborate fake. Most in the press are sceptical about its contents, given the level of detail, and have written caveat-laden reports just like this one.

At the very least, it's a thought-provoking look at what Xbox's biggest, most attentive fan-cum-hoaxer would like to see.
